TO ALL WHOM IT MAY- CONCERN: L

Be it known that ne, EDWARD A. SMITH, of St. Albnns, in the Seite of Vermont, and 'Hnsxmm Gr'mrn, lof Goshen, in the State of Connecticut, have invented, mode, and npplied to use, ecertnin new and useful Improvement in Mening and Renping-Machnes; und we do hereby declare the following to bea full, clear,

and exact description of. the said invention, reference' being. had to the nnnsired'drowing, making part of thisspeciention, wherei'ni Figure 1 is u plan `oi' our improvement, n nd Figure 2 is e vertical section at the line :c z. The sume ports nro'denoted by corresponding letters. l y `Heretofore the connecting-rod from the crank to the cutter-bnr' has passed intol cholo init piece of iron nttnched to the upper and inner end of the cutter'bur. It is very diilicult to prevenjivenr in the hole of this cutter-bar connectionfand the noise und injury nre constantly increased ns the parte we's'r army.

Our invention relates to the manner of makingthls connection between the connecting-rod und cutter-bnr, nnd consists in a bush introduced in tho cutter-bnr connection, and .applied in such a manner that the friction will be very much lessened, y:ind that the bush cnn be removedend nnother substituted when worn Thus our machine is rendered much more durable than heretofore, and considerable noise is prevented."

In the drawing, o is the bar carrying the cutters b b'. c is, the ir'n bur sttachedubove-the cutters, ntl the inner end of the cutterbnr, ond d is a. port of the connecting-rod, formed with a cylindrical end, that ordinarily passes into the part c, a hole beingv provided for it." We however introduce the movable bush'e, made of brass or similar metal, to lessen the friction und prevent the ports becoming rested` together whennot in use.

This bushe is mede with n flange, 2, entering n recess in the -bnr c, so os to be almost hush with the seme, and 3 is n groove turned in the exterior of scid bush c, to form un oil-receptacle,- communicntiug, by u hole, to the journal on .the end of the connecting-mdd. Y

iris en oil-cup screwed through c, with its end entering the groove 3, but not setting therein so tightly us to prevent oil passing freely to the parts to belubriccted.

The bush e may be free to turn vvhile in use, or it may be .moved around progressively, from time tc time, und prevent the weer being in one place. v s l What we claim, and desire to secure by Letters Patent, is-

p The bush e, mede as set forth, ondA introduced in the end of the cnttelrl-hnr, to receive the journal of the convnectingq-O, in combination withthe oil-receptacle es und for the purposes set forth.

In witness whereof, we have hereunto set cnr signotrcs, this 7th doy of September, 1867.
